[APEXCORE-528] Fix OutputPort Default Optional Behavior
This PR removes the validation logic that requires output ports to be
connected if not explicitly annotated as optional. This change complies with
the behavior defined by the optional annotation as it states they should be
optional by default.

> Output Ports Not Optional by Default During Validation
> ------------------------------------------------------
>
> Key: APEXCORE-528
> URL: https://issues.apache.org/jira/browse/APEXCORE-528
> Project: Apache Apex Core
> Issue Type: Bug
> Affects Versions: 3.4.0
> Reporter: Alex McCullough
> Assignee: Alex McCullough
> Priority: Minor
>
> The 'optional' OutputPortFieldAnnotation states that the default value is
> true. When you build a DAG with multiple output ports the validator throws an
> error telling you at least one must be connected. To fix, you must explicitly
> add the annotation to all output ports and set the value to True, which is
> supposed to already be the default.
